Application filed June 7,

To all whom it may concern:

Be it known that I, CLAUDE A. MALLoRY, a citizen of the United States, residing at Madison, in the county of Lake and State of South Dakota, have invented new and useful Improvements in Reflectors, of which the following is a specification.

This invention relates to improvements in reflectors, the general object of the invention being to provide means for reflecting the rays of light upon an object, the invention bei-ng more especially designed for use in photography.

"Another object of the invention is to provide a frame with a plurality ofv reflectors therein, each reflector being formed of a single piece of material which supports the mirrors.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts 4throughout the several views, and in which:

Figure 1 is a sidevview of the invention.

Figure 2 is a front view' thereof.

Figure 3 is a front view of the reflectors.

Figure 4 is a section on line 4-4 of Figure 3.

Figure 5 is a section on line 5-5 of Figure 3.

Figure 6 is a view of the blank from which the mirror support of the reflector is formed.

` Figure 7 is a detail view of the means for holdin the lamp socket.

In t ese views 1 indicates a wheeled base which supports the upri hts` 2. A bar?) is slidably mountedion eac u right and this bar has a rack 4 thereon w ich is en aged by a toothed wheel 5 on a shaft 6 which is mounted in brackets 7 secured to the u rights. This shaft is provided with a' handle 8 and with ratchet mechanism 9 for holding` it in adjusted position. By this means the rods 3 may be raised or lowered as desired. A reflector frame 10 is pivotally secured to the upper ends of the rods 3, the frame being held in adjusted position by the nuts 11. A diffusion screen 12 is supported by the arms '13 which are pivotally secured to the ma. serial 1ro. 566,454.

screen and these arms are adjustably secured to the uprights 3 by the set screws 14, the arms passing through holes formed in parts on the rods and set screws pass through these parts andengage the arms. A reflecting screen 15 is adjustably secured to the frame 10, as shown at 16, and a screen 17 is adjustably connected with the top of the frame 10, as shown at 18. These screens 15 and 17 may be composed in part of white cloth or metal and` act to reflect the rays of light from the reflector 10.

The reflector frame carries a number of reflectors 19, each of which is 'provided with a lamp 20. Each reflector has its base formed of a single bent as shown in igures 4, 5 and 6. This piece 19 is cut, as shown at 21, and the small strip 22 is lapped over the opposite edge of the cut part. The blank is bent on the converging lines 23 so that when the strip 22 is secured to the adjacent part the blank will assume a flat pyramidal form. The corners of the blank are cut away, as shown at 24, and the edges of thev blank are bent to form the main flanges 25 and the small flanges 26, these small flanges 26 being located in the corners. Four triangular mirror stri s 27 are placed in each reflector, the str1p being held in by bending the flanges 26 over the corners, the extremities of said flanges 26 being bent down to engage the edges of the strips. The pointed ends of the mirror strips are held in place by a flexible washer 28 and the bolt 29 which passesthrough the center of the base. Some of the flanges 25 are secured to the frame 10 while others are bent and fastened together,l as shown at 30. The cutaway corners of the blanks leave openings 31 which provide ventilatin openings for vthe device and also permit t e conductor wires to the lamps 20 to pass through. The lamp sockets 32 are carried by the threaded members 33 which are adjustabl mounted on the brackets 34, connected w1th the frame 10, by the nuts 35. Thus t e lamps may be adjusted relative to the re ectors.

Figures 1 and 2 simply show one way derstood that this frame can be used in a number of different ways. The improved reflector frame will permit a small bulb'to be used and the light will be thrown over a broad area. Pictures can be made with my reflector with far less electric,A current than iece of material cut and:

of usmg the reflector frame as it will be unwith ordinary reflectors. The fact that the light comes from several points broadens the effect andmakes the shadows less shar By getting the volume of light without ta ing it all from one little spot gets away from a large amount of glare always res ent where a large amount of light comes fiom a very small spot. This is decidedly noticel able in using a ron7 of these reflectors. There is absolutely no strain on the eyes or glare of any kind and while there is a good Working light there is less glare than if stronger bulbs were used that really give less to Work by. It represents a more truly daylight effeet both to the eyes of those working with it and in the finished picture as well. It can be reflected on the shadow side of the picture the saine as though it were light from a skylight. Pictures made with a row of these reflectors show a longer scale of shadow tone than ordinary electric results.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A device of the class described comprising a frame, a plurality of reflectors in the frame, each reflector consisting of a base formed of a single piece of material formed into a flat p ramid, mirror strips restin against the inner sides of the pyrami flanges on the base bent over the mirror strips to hold them in place, flan es on the base adapted to be secured to the rame and to flanges of other bases and an electric lamp associated With each reflector.

2. A device of the class described comprising a frame, a plurality of reflectors in the frame, each reflector consisting of a base formed of a single piece of material formed into a flat pyramid, mirror strips restin against the inner sides of the pyramid, anges on the base bent over `the mirror strips to hold' them in place, flanges on the base adapted to be secured to the frame and 'to flanges of other bases, an electric lamp associated with each reflector, and means for adjusting the lamp transversely in relation to the center of the reflector.

3. A reflector of the class described comprising a frame, a plurality of reflectors placed in the frame, each reflector comprising a base of pyramid shape and mirror I strips placed upon. the inner faces of thc pyramid base, flanges upon the base for engaging the stiips, a b olt passing through the apex of each base and a flexible Washer on each bolt for engaging the pointed ends of the mirror strips.

4. A device of the class described comprising a reflector frame, a lurality of reflectors therein, a lam associated lwith each reflector` an adjustab e support for the reflector frame, screens adjustably connected with the reflector frame arm' slidably connected with the frame and a screen carried by said arms in front of the frame.

, In testimony whereof I ax my signature.
